"When Balak took Bilaam"
We are told that Bilaam went up to the altars of Ba'al because he foresaw that Yisrael would come to worship Ba'al in the future. Bilaam wanted to provoke a quarrel with Yisrael yet he saw he could not because of their friendship with God, so he made a sacrifice to God that was rejected. Bilaam told Balak to restrain Malchut with his witchcraft, and, if he could do that, he himself would nullify the blessings he had given Yisrael. Yet Rabbi Yitzchak says that Yisrael could be cursed neither from the aspect of the patriarchs nor the matriarchs. The rabbis talk about various sections of this scripture - the top of the rocks, the dust of Jacob, and the fourth part of Yisrael. In the end we hear that Bilaam saw that even with all his witchcraft and his offerings he would be unable to sever Yisrael from God, so he was powerless. He had tried to breach Yisrael's defences at the level of Jacob and at the level of Israel, but was unable to because neither level is ever involved in evil actions. We hear that there are two Klipot of iniquity and perverseness that correspond to enchantment and divination; Bilaam thought these would be the right weapons against Jacob and Israel, but he was wrong. The rabbis say that Yisrael is as strong as a lion and will conquer the heathen nations in the future. Rabbi Aba also refers to the form of a lion that appears on top of acceptable burnt offerings. If the form of a dog appeared on the fire it meant that Yisrael must repent. Rabbi Elazar returns to the story of Bilaam and tells Rabbi Yosi that at the moment Bilaam turned his evil eye to Yisrael, God protected them by covering them with His spirit. Bilaam praised Yisrael so that his evil eye would be more effective and they would be more vulnerable to it, but God did not allow him to harm Yisrael. Yisrael is never afraid, even in exile, because they have the strength of a lion due to their study of the Torah and their obedience to its laws.
